Confused, how to remove stats from Novus?

[Steady]

edit:

actually I got a better question:

I got the scroll now with 75/75 ready for modification. I took the option on Novus, what if I get my Lights upgraded to Nexus before I do the modification. Would that scroll still works that I previously pick Novus option?

The scroll is seperate and the same for all stages of Bravura->Ragnarok. or in your case Thryrus/Nirvana. You can get your scroll, alter it... and choose to use it at any time.

I do not know how it affects lights.
